+//===- Linker.cpp - Module Linker Implementation --------------------------===//
+//
+// This file implements the LLVM module linker.
+//
+// Specifically, this:
+//  - Merges global variables between the two modules
+//    - Uninit + Uninit = Init, Init + Uninit = Init, Init + Init = Error if !=
+//

+// LinkModules - This function links two modules together, with the resulting
+// left module modified to be the composite of the two input modules.  If an
+// error occurs, true is returned and ErrorMsg (if not null) is set to indicate
+// the problem.
